System (DCS) and Supervisory control and Data
Acquisition system (SCADA) will be installed to
control & monitor all the remote stations /
facilities; build operation center which covers
offices, warehouse & staff accommodation with all
related facilities which will enable the operator to
monitor and supervise the entire process.
Al-Ansab plant is based on using the Membrane
Bioreactor (MBR) Technology which is considered as
one of the leading technologies in the Industry.
Once commissioned, Al-Ansab plant will be the
largest of its kind worldwide using the MBR
technology. The plant capacity is 53,000 m3/day.
The Contractor, M/s. Galfar Engineering &
Contracting Co. LLC has started the construction
activities.
